rose Posted June 29, 2017 Share Posted June 29, 2017 (edited) Yesterday I have seen an article about audio power amplifier based on TDA2030AH in a bridged connection with a +/- 15V symmetric PS. According to the datasheet of TDA2030AH displays，TDA2030AH integrates circuits are very cheap and use-full if you want to start a small audio amplifier. The only thing you have to consider is to use a good power supply and heatsink or you’ll risk to burn this precious IC amplifier. The TDA2030 is a monolithic integrated circuit in Pentawatt package, intended for use as a low frequency class AB amplifier. Typically it provides 14W output power (d = 0.5%) at 14V/4W; at ± 14V or 28V, the guaranteed output power is 12W on a 4W load and 8W on a 8W. I have built this circuit and it is totally fine, it works the same way as the monolithic version.About the supply, 15v is not needed to be exactly as it is, it is 12-18v depends on power output desired, and about that split type supply, you can use an ordinary 12v DC supply, just use two polarized capacitors to create a ground line for the circuit.

CECAA850 Posted June 29, 2017 Share Posted June 29, 2017 How does it sound and what speakers are you using with it? Quote Link to comment Share on other sites More sharing options...
djk Posted June 29, 2017 Share Posted June 29, 2017 The 2030 is limited to 3.5A peak current output, inadequate for a bridged amp of any voltage. The schematics on the data sheet are suggestions, and not to be taken as a complete design. Quote Link to comment Share on other sites More sharing options...
